In quantum mechanics, wave function collapse (also called collapse of the state vector or reduction of the wave packet) is the phenomenon in which a wave function—initially in a superposition of ...

They ask us to believe, for example, that the world we experience is fundamentally divided from the subatomic realm it’s built from. Or that there is a wild proliferation of parallel universes, or ...

One of the most important paradoxes in physics is Schrödinger's Cat. At the microscopic level, light and particles behave according to quantum mechanics. This allows them to be in two places at once ...
